Objectives: To evaluate the adhesive remnant index (ARI) of orthodontic brackets bonded with two adhesive systems using two different light curing times.

Materials and methods: Fifty-six extracted premolars were divided into two groups (n= 28) depending on the type of adhesive system used; Total-Etch (TE) Transbond XT and Self-Etch (SE) Transbond Plus. Each group was subdivided into two subgroups (n= 14) based on the curing time; 20 seconds and 3 seconds. The ARI was evaluated in each subgroup. The significance level was set at P≤ 0.050.

Results: The ARI showed that there was a statistically significant difference in ARI between the 4 groups (H [3] = 22.832, p-value

Conclusions: Varying the adhesive system results in different ARI scores, which can affect the enamel surface during debonding. While reducing the curing time did not show a significant impact on the ARI.
